The bifold door required must be 40'Wx18'H. Wind rating is very important and will likely be the determining factor on which product I purchase due to my location. Please send all information via email. Thank you.


I have a customer interested in building a new hangar in Alaska. They want a single 42'x14' clear lift-strap bi-fold door. We are getting a quote for the structure and would like to get a quote and spec from Schweiss Doors to accompany that. The bi-fold door with need to be wind loaded as the wind load is 110 mph with a wind exposure B or C, and the snow load is a 40 lb. roof load.


Do you have any suggestions on an uninsulated door for a new hangar needing an opening of 25 metres wide x 7 meters high. I am considering a lift-strap bifold door after reading your site. Does it make a difference if it is a end wall  or a side wall? The temperatures in New Zealand are not much of a problem [40F-80F], but it does blow about 50 knots commonly! Thanks, Gerald G.


I'm interested in a one piece hydraulic 42'x16' aircraft hangar door for a hangar I'm building in Florida. The local code requirement is that the door be 180mph wind rated. It would be a basic door with no entry door in it. Would you please let me know what options are available. Do you have installers available or do general contractors usually do it? Thanks Darrell F.


I have had one of your doors for many years, & have liked it. We had a very bad storm (tornado) & it tore the door completely off & is now laying on top of the building. It looks pretty bad, so I think we are going to need a new Schweiss wind loaded door. Could work up a price on a 20X14 hydraulic door and bifold strap door. I believe your new strap latch that secures the door positively to the building may be just what we need to conquer the next big storm. Thank You, Charlie

Here I am again, needing a price for some bi-fold doors. If you keep making them, I\'ll keep buying them. This project is here around the Houston Area in a 90 MPH wind area. Project is needing (10) 40%u2019-0 x 14%u2019-0 bi-folds with liftstraps and autolatches and walk doors. The doors would be furnished with all the electrical and, we would be furnishing the panels at the face to match the building. Right now this is all the information that I have for you.

Please advise if Fl. wind and hurricane code compliance requires additional cost on your Schweiss hydraulic doors. Please do not share this info with my designer or builder, for obvious reasons, they will not be building in Fl. for me.


I recently bought property that has a 115x70 ft hanger with very cheap roller doors. I must upgrade the doors before these drive me crazy. I\'ve seen the Schweiss bi-fold doors, hydraulic doors at other hangars in the three-state area and believe my option will be to go to your new Red Power hydraulic model . My door opening is 75x16 ft. I live 38 miles from the gulf so strength has to be #1 priority


Thanks for taking the time to speak with me this afternoon. What the CHP is looking for is something that says your doors are safe to operate in winds up to 40 mph. Your standard spec sheet lists max operating speed as 30 mph, however, the CHP still will operate aircraft in 30 mph winds. They ground their aircraft at 40 mph or redirect them to other airfields. Can you provide me with a letter or statement reinforcing our conversation that your bifold liftstrap and hydraulic Red Power doors are able to operate/be moved to the closed or open position in winds speeds up to 40 mph? Please let me know if you have any questions, and again thanks for your help. Regards
